Preparation method of boron carbide ceramic and application of boron carbide ceramic in bulletproof helmet
The invention relates to the technical field of preparation and application of advanced ceramic materials, in particular to a preparation method of boron carbide ceramic and application of the boron carbide ceramic in bulletproof helmets, and relates to a method for preparing a high-performance boron carbide ceramic material and application of the high-performance boron carbide ceramic material in bulletproof helmets. After a green body is pressed, whether the compactness of the green body meets the standard or not is determined according to the comparison result of the helium content detected by a helium leak detector and a preset helium comparison value, and if not, the pressure maintaining time and the pressing speed of a pressing machine during green body pressing are adjusted according to the helium content value. Or the pressurization pressure of the pressing machine during blank pressing is adjusted, and the operation parameters of the pressing machine during blank pressing are controlled, so that the boron carbide ceramic with the characteristics of high hardness, high strength and light weight can be produced, and the protection performance of the bulletproof helmet is remarkably improved.
本发明涉及先进陶瓷材料制备及应用技术领域，尤其涉及一种碳化硼陶瓷的制备方法及其在防弹头盔中的应用，本发明涉及一种用于制备高性能碳化硼陶瓷材料的方法，以及该材料在防弹头盔中的应用。通过在压制坯体后，根据氦气检漏仪检测的氦气含量与预设的氦气对比值的比对结果确定坯体的致密性是否符合标准，若否，则根据所述氦气含量值调整在压制坯体时压制机的保压时间及压制速度，或调整在压制坯体时压制机的加压压力，通过控制压制坯体时压制机的运行参数，本发明能够生产出具有高硬度、高强度和轻质特性的碳化硼陶瓷，显著提升防弹头盔的防护性能。
